Two kids play on a seesaw that has mass 20 kg, length 3 m, and its fulcrum at its mid-point. The seesaw is originally horizontal, when the kids sit at the edge of opposite ends (m,_LEFT = 25 kg, m,_RIGHT = 30 kg). Calculate the Net Torque from the 3 weights acting on the seesaw, immediately after the kids sit (simultaneously) on their respective places.

• A. 75 N•m clockwise
• B. 75 N•m counterclockwise
• C. 150 N•m clockwise
• D. 150 N•m counterclockwise
